1 Jessica SimpsonOnce, people said that Jessica Simpson could become a viable acting proposition. Then people saw Jessica Simpson act. And now nobody says that any more.Pictured: Blonde Ambition (2007)

2 Michael JacksonIn Moonwalker, Michael Jackson played himself. Not a version of himself. He actually played himself, but with all the panache of a regional Michael Jackson lookalike competition bronze medal winner. Let us call this the Spice World effect.Pictured: Moonwalker (1988)

3 PrincePrince can compose, perform, produce, sing and dance like nobody else on earth. He can also act like nobody else on earth. Because everyone else on earth is better at it than him.Pictured: Purple Rain (1984)

5 50 CentLike Eminem, 50 Cent essentially played himself in Get Rich or Die Tryin’. Unlike Eminem, he then made lots of direct-to-DVD filler that people only watch out of self-loathing.Pictured: Get Rich or Die Tryin' (2005)

6 Britney SpearsIt’s easy to pick on Britney Spears for starring in Crossroads, but that’s because watching Crossroads was like performing dental surgery on yourself with a tinfoil drill. Her place here is well deserved.Pictured: Crossroads (2002)

7 Pete DohertyDoherty’s debut acting turn alongside Charlotte Gainsbourg in Confession of a Child of the Century was labelled as “shambling amateurism” by the Guardian’s Catherine Shoard. And that was her being nice.Pictured: Confession of a Child of the Century (2012)

8 RihannaAdmittedly Rihanna wasn’t given an awful lot to do in Battleship, but she still failed hopelessly at it. Your mum, given the chance, could grunt at a Transformer more convincingly.Pictured: Battleship (2012)

10 Geri HalliwellOne scene in an episode of Sex and the City. A cameo in Crank: High Voltage. Fat Slags. That’s all of Geri Halliwell’s acting career. Oh, and she was in Spice World. I rest my case.Pictured: Spice World (1997)
